TECHNICAL FIELD

The present disclosure generally relates to wearable devices for interacting with user interfaces. For example, aspects of the present disclosure relate to using a wearable ring device to interact with electronic devices and user interfaces such as extended reality (XR) interfaces on XR devices.

BACKGROUND

Extended reality (e.g., augmented reality, virtual reality, etc.) devices, such as smart glasses and head-mounted displays (HMDs), generally implement cameras and various sensors to track the position of the extended reality (XR) device and other objects within the physical environment. The XR reality devices can use the tracking information to provide a user of the XR device a realistic XR experience. For example, an XR device can allow a user to experience or interact with immersive virtual environments or content. To provide realistic XR experiences, XR technologies can integrate virtual content with the physical world, which can involve matching the relative pose and movement of objects and devices. The XR technologies can use tracking information to calculate the relative pose of devices, objects, and/or maps of the real-world environment in order to match the relative position and movement of the devices, objects, and/or the real-world environment, and anchor content to the real-world environment in a convincing manner. The relative pose information can be used to match virtual content with the user's perceived motion and the spatio-temporal state of the devices, objects, and real-world environment.

DETAILED DESCRIPTION

Certain aspects and embodiments of this disclosure are provided below. Some of these aspects and embodiments may be applied independently and some of them may be applied in combination as would be apparent to those of skill in the art. In the following description, for the purposes of explanation, specific details are set forth in order to provide a thorough understanding of embodiments of the application. However, it will be apparent that various embodiments may be practiced without these specific details. The figures and description are not intended to be restrictive.

The ensuing description provides example embodiments only, and is not intended to limit the scope, applicability, or configuration of the disclosure. Rather, the ensuing description of the exemplary embodiments will provide those skilled in the art with an enabling description for implementing an exemplary embodiment. It should be understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the application as set forth in the appended claims.

As previously mentioned, extended reality (e.g., augmented reality, virtual reality, etc.) devices, such as smart glasses and head-mounted displays (HMDs), generally implement cameras and various sensors to track the position of the extended reality (XR) device and other objects within the physical environment. The XR reality devices can use such tracking information to provide a user of the XR device a realistic XR experience. For example, an XR device can allow a user to experience or interact with immersive virtual environments or content. To provide realistic XR experiences, XR technologies can integrate virtual content with the physical world, which can involve matching the relative pose and movement of objects and devices. The XR technologies can use tracking information to calculate the relative pose of devices, objects, and/or maps of the real-world environment in order to match the relative position and movement of the devices, objects, and/or the real-world environment, and anchor content to the real-world environment in a convincing/realistic manner. The relative pose information can be used to match virtual content with the user's perceived motion and the spatio-temporal state of the devices, objects, and real-world environment.

In some cases, XR devices can be paired with controllers that users can use to select and interact with content rendered by the XR devices during an XR experience. To enable realistic interactions with rendered content using controllers, the XR devices can use the cameras and other sensors on the XR devices to track a pose and movement of the controllers, and use the pose and motion of the controller to match the state of the controller with the user's perceived motion and the spatio-temporal state of rendered content and other objects in the environment. However, controller-based XR systems often require a significant amount of power and compute resources to implement, which can negatively impact the performance and battery life of the XR devices used with the controllers. Moreover, the use of controllers may not be intuitive for the user and, in many cases, can be difficult to use. For example, controllers can be difficult to use when the user of the controller is in certain positions, such as lying down or reclined. Controllers can also be difficult to use in space-constrained environments such as airplanes, crowded areas, etc.

In many cases, controllers used with XR devices can also create privacy issues. For example, a person or computer with visibility to the user of the controller can analyze the user's movements and interactions with the controller to recognize the user's interactions with the content rendered by the XR device during the XR experience as well as associated information, potentially putting the privacy of the user's information at risk. In some examples, an artificial intelligence (AI) interpreter or system can be used to process a recording of the user's interactions and identify the information provided by the user through the rendered XR interface. The AI interpreter or system could potentially recognize the information provided by the user through the XR interface. Accordingly, when a user is engaged in an XR experience using a controller associated with an XR device, the user could potentially expose inputs and associated information to other users, such as user selections, Personal Identification Numbers (PINs), gestures, etc. The user may want to protect the privacy of interactions with XR interfaces rendered by the XR device even if other users are not also engaged in the same XR experience as the user or able to see the XR interface.

In some aspects, systems, apparatuses, processes (also referred to as methods), and computer-readable media (collectively referred to herein as “systems and techniques”) are described herein using a wearable device/accessory that interfaces/interacts with an electronic device (e.g., an XR device, a mobile device, a television, a smart wearable device, an electronic device with a user interface, or any other electronic device) to provide enhanced user interface, input, and/or XR experiences and functionalities. In some examples, a wearable accessory can be used with XR devices to securely and intuitively provide XR inputs and interact with XR content. The wearable accessory can include one or more sensors to assist with tracking, gesture detection, and/or content interaction functionalities, among others.

In some cases, the wearable accessory can be a ring or ring structure that can be worn on a user's finger or hand. A user can use the ring or ring structure during an XR experience to provide one or more types of inputs to an XR device providing the XR experience. The XR device can detect different modes of input, which can be converted (e.g., interpreted as, mapped to, etc.) into specific inputs and/or functionalities. For example, a user can wear a ring on a particular finger and rotate the ring about a longitudinal axis of the user's finger to scroll through content, manipulate rendered content, manipulate the XR environment, select content, generate measurements in the physical world, etc. As described herein, a longitudinal axis is generally parallel to a receiving space (e.g., a lumen) of the wearable accessory that provides a longitudinal access opening for a finger and at least a portion of the finger wearing the wearable accessory. A lateral axis is normal to the longitudinal axis and a transverse axis extends normal to both the longitudinal and lateral axes. The longitudinal direction is a direction substantially parallel to the longitudinal axis, the lateral direction is a direction substantially parallel to the lateral axis, and the transverse direction is a direction substantially parallel to the transverse axis.

Other example ways the user can provide an input to the XR device using the ring can include tapping the ring with a different finger than the finger wearing the ring, squeezing the ring with one or more fingers that are adjacent to the finger wearing the ring, rotating or swiping the ring with a finger such as a thumb, rotating or swiping the ring with one or more fingers that are adjacent to the finger wearing the ring, and/or otherwise physically interacting with the ring. In some cases, the user can use motion of the finger wearing the ring and/or the hand to provide one or more types of inputs to the XR device based on the tracked motion of the finger and/or the hand. In some examples, the ring can include one or more sensors to detect such motion and/or interactions with the ring. The ring can include a wireless interface to send measurements corresponding to detected inputs to the XR device.

In some cases, different modes of input using the ring can correspond to, and/or can be converted into (e.g., interpreted as), different types of XR inputs. For example, the user can rotate the ring about a longitudinal axis of the finger wearing the ring and/or rotate a rotatable portion of the ring about a longitudinal axis of the ring and relative to another portion of the ring to scroll through content, forward or rewind a video or any other sequence of content, move rendered content (e.g., rotate content, etc.), navigate content, etc. As another example, the user can tap or swipe the ring to perform a selection; move the finger wearing the ring (and/or the hand with the finger wearing the ring) to provide gestures, manipulate XR content and/or environments, define a plane, create XR spaces and/or content, etc.; among other things. In general, because of the configuration of the ring (e.g., the size, shape, etc.) and how it is used by the user (e.g., worn on a finger, wrist, etc.), user interactions with the ring can be more discreet, inconspicuous, and/or otherwise harder to detect/notice than user interactions with a different controller device. Thus, the privacy and associated data of XR inputs provided via the ring on the user's finger can be better protected from people and other devices in the environment. Moreover, the user can easily and conveniently provide inputs using the ring even when the user is in space-constrained areas, lying down and/or otherwise positioned in way that would be difficult to otherwise move a controller to generate an input.

In some cases, the ring can reduce power consumption and resource usage at the XR device. For example, the ring can offload certain operations such as hand tracking and/or other tracking operations from the XR device, allowing the XR device to reduce power consumption and resource usage such as sensor, camera, and/or compute resource usage. In some examples, when tracking operations are offloaded from the XR device to the ring, the XR device can turn off, or reduce a power mode of, one or more tracking resources such as cameras and/or other sensors that the XR device would otherwise use to track the user's hands and/or other objects.

The ring can include one or more sensors to track and detect activity such as, for example, motion, inputs, etc. For example, the ring can include a rotary encoder to track rotation and/or swiping of the ring (and/or portions thereof) for one or more types of inputs. An inertial measurement unit (IMU) in the ring can integrate multi-axes, accelerometers, gyroscopes, and/or other sensors (e.g., magnetometers, etc.) to provide the XR device an estimate of the hand's pose in physical space. One or more sensors in the ring, such as ultrasonic transmitters/transducers and/or microphones, can be used for ranging of the hands. In some examples, one or more ultrasonic transmitters/transducers and/or microphones can help determine if the user's hands are closer together or farther apart, if any of the user's hands are close to one or more other objects, etc. In some examples, a barometric air pressure sensor in the ring can determine relative elevation changes and can be used to interpret selection events. The ring can send measurements from one or more sensors to the XR device, which can convert the sensor measurements into user inputs. The ring can provide new user experience (UX) functionalities that enable easier, more intuitive actions by the user, and enable various types of actions based on sensor inputs.

In some examples, the ring can enable scrolling and other actions via one or more interactions with the ring. For example, in some cases, the ring can include an outer ring and an inner ring. The outer ring can spin around and/or relative to the inner ring. The ring can include a rotary encoder to detect a rotation magnitude. The ring can send the rotation magnitude to the XR device, which can convert the rotation magnitude into an input such as a scroll magnitude. In some cases, the entire ring can spin around the user's finger (or a portion of the user's finger), and an IMU in the ring can detect the spin motion to determine an input such as a scroll magnitude. In some cases, the ring can include a touch sensor to provide touch sensitivity at one or more areas of the ring and/or across a surface of the ring to detect touch inputs such as a selection, a scroll magnitude, etc. In some examples, a touch sensor can be positioned on an outside of the ring, making the ring non-symmetric. The touch area can be akin to a small touch pad and can be used by a different finger to provide inputs. For example, the touch area can be akin to a small touch pad that can be used by a thumb when the ring is on the index finder.

The ring can be equipped with various power saving features. For example, in some cases, the ring can save power by shutting down after the XR application on the XR device has stopped and/or been terminated. As another example, the ring can remain off or in a lower power mode, and turn on or switch to higher power mode based on one or more user interactions/inputs. For example, the ring can remain off or in a lower power mode, and turn on or switch to higher power mode when the ring is rotated by a certain amount.

The ring can provide privacy benefits, as previously explained, as well as other benefits. For example, with the ring, the user does not have to (but can) wave any hands or fingers in the air to generate an input. As another example, the ring can conserve power of the XR device by providing tracking functionalities and allowing the XR device to turn off or power down resources on the XR device such as, for example, cameras, tracking sensors, etc. In some cases, the ring can include a processor or chip that provides various functionalities, and can interact with a processor and/or chip on the XR device.

The discussion begins with a description of example systems and techniques for providing enhanced XR functionalities/experiences using a ring device, as illustrated in FIGS. 1 through 5 .

In some cases, the one or more other sensors 106 can detect acceleration by the XR system 100 and generate acceleration measurements based on the detected acceleration. In some cases, the one or more other sensors 106 can additionally or alternatively detect and measure the orientation and angular velocity of the XR system 100. For example, the one or more other sensors 106 can measure the pitch, roll, and yaw of the XR system 100. In some examples, the XR system 100 can use measurements obtained by the one or more other sensors 106 to calculate the relative pose of the XR system 100.

The ring device 150 can use the IMU 152, the position sensor 154, the pressure sensor 156, and/or the touch sensor 158 to detect inputs for the XR system 100, as further described herein. The ring device 150 can detect one or more modes of input such as for example and without limitation, applying a force (e.g., tapping, squeezing, pressing, rubbing, swiping, touching, etc.) on one or more portions of the ring device 150, rotating and/or swiping one or more portions of the ring device 150, etc. The ring device 150 can provide one or more detected inputs to the XR system 100 to modify a content, operation, and/or behavior of the XR system 100.

In some cases, the ring device 150 can calculate a magnitude of an input and provide the magnitude of the input to the XR system 100 as part of a provided input. For example, the ring device 150 can calculate a magnitude of a force and/or rotation applied on the ring device 150 and provide the magnitude of force and/or rotation to the XR system 100 as an input. The XR system 100 can use the magnitude information to determine a type of input (e.g., a single click, double click, selection, scroll, gesture, object resizing, control input, settings input, etc.) and/or an input magnitude (e.g., an amount of scrolling, object resizing, environment/object manipulation, etc.).

In some examples, the ring device 150 and/or the XR system 100 can use measurements obtained by the IMU 152, the position sensor 154, and/or the pressure sensor 156, to calculate (and/or to assist in calculating) the location and/or relative pose of the ring device 150. In some cases, the IMU 152 can detect an orientation, velocity (e.g., rotational, linear, etc.), and/or acceleration (e.g., angular rate/acceleration, linear acceleration, etc.) by the ring device 150 and generate orientation, velocity and/or acceleration measurements based on the detected orientation, velocity, and/or acceleration. For example, in some cases, a gyroscope of the IMU 152 can detect and measure a rotational rate/acceleration by the ring device 150 (and/or a portion of the ring device 150). In some examples, the IMU 152 can additionally or alternatively detect and measure linear velocity and/or acceleration by the ring device 150. In some examples, the IMU 152 can additionally or alternatively detect and measure an orientation of the ring device 150. In some cases, the IMU 152 can additionally or alternatively detect and measure the orientation and angular velocity of the ring device 150. For example, the IMU 152 can measure the pitch, roll, and yaw of the ring device 150.

In some examples, the position sensor 154 can calculate a position of the ring device 150 in terms of rotational angle, linear motion, and three-dimensional (3D) space. For example, the position sensor 154 can detect a rotation and/or spin of the ring device 150. The pressure sensor 156 can detect pressure such as air pressure, and can determine relative pressure changes. In some examples, measurements from the pressure sensor 156 can be used as inputs to interpret content selection events. The touch sensor 158 can measure physical forces or interactions with the ring device 150, which can be interpreted as inputs to the XR system 100, as further described herein.

The ring device 150 can include one or more wireless communication interfaces (not shown) for communicating with the XR system 100. The one or more wireless communication interfaces can implement any wireless protocol and/or technology to communicate with the XR system 100, such as short-range wireless technologies (e.g., Bluetooth, etc.) for example. The ring device 150 can use the one or more wireless communication interfaces to transmit sensor measurements and/or other XR inputs to the XR system 100, as further described herein.

While the XR system 100 and the ring device 150 are shown to include certain components, one of ordinary skill will appreciate that the XR system 100 and the ring device 150 can include more or fewer components than those shown in FIG. 1 . For example, the XR system 100 and/or the ring device 150 can also include, in some instances, one or more other memory devices (e.g., RAM, ROM, cache, and/or the like), one or more networking interfaces (e.g., wired and/or wireless communications interfaces and the like), one or more display devices, caches, storage devices, and/or other hardware or processing devices that are not shown in FIG. 1 . An illustrative example of a computing device and hardware components that can be implemented with the XR system 100 and/or the ring device 150 described below with respect to FIG. 7 .

FIG. 2A illustrates an example of the ring device 150. The user can use the ring device 150 to interact with the XR system 100 and provide various types of XR inputs as further described herein. In some examples, the ring device 150 can collect sensor measurements to track a location and/or pose of the ring device 150 in 3D space. In some examples, the location and/or pose can be tracked relative to a location and/or pose of the XR system 100 in 3D space.

In this example, the ring device 150 includes a structure 200 (or body) that has a receiving space 210 that provides a longitudinal access opening disposed on the underside of the structure 200 to allow at least ingress of a finger of a user, a first surface 212 (or internal surface) that can provide an engagement surface for a finger inserted through the receiving space 210 to wear the ring device 150, and a second surface 214 (or external surface). The structure 200 can also include one or more sensors and/or electronic components as described herein. In this example, the structure 200 includes a touchpad 204 for receiving touch inputs, a display 206 for displaying information from the ring device 150 and/or the XR system 100, and sensors 208. In some examples, the sensors 208 can include and/or can be the same as the IMU 152, the position sensor 154, the pressure sensor 156, and/or the touch sensor 158 shown in FIG. 1 . In other examples, the sensors 208 can include one or more sensors and/or devices that are not shown in FIG. 1 , such as one or more cameras, light sensors, audio sensors, lights, etc. In some cases, the ring device 150 can include a touch or pressure sensitive surface and/or surface portion for measuring touch inputs.

The receiving space 210 can be configured to receive a finger of a user. For example, as noted above, the receiving space 210 can include a longitudinal access opening disposed on the underside of the structure 200 to allow at least ingress of a finger of a user. The first surface 212 can provide an engagement or retention surface for the finger of the user. The first surface 212 can be contoured and/or shaped so as to support/retain the finger of the user within the receiving space 210 and inhibit or prevent movement of the finger in the longitudinal, lateral, and/or transverse axes/directions relative to the receiving space 210.

A longitudinal axis is generally parallel to the receiving space 210 and at least a portion of a finger wearing the ring device 150 (e.g., a finger retained by the first surface 212 of the structure 200). A lateral axis is normal to the longitudinal axis and a transverse axis extends normal to both the longitudinal and lateral axes. The longitudinal direction is a direction substantially parallel to the longitudinal axis, the lateral direction is a direction substantially parallel to the lateral axis, and the transverse direction is a direction substantially parallel to the transverse axis.

The second surface 214 can include an external surface of the structure 200. The external surface can include a top or upper surface of the structure 200. In some examples, a user wearing the ring device 150 on a finger can interact with the second surface 214 (e.g., using a different finger than the finger wearing the ring device 150 and/or using any other object) to provide inputs measured by the sensors/components (e.g., touchpad 204, display 206, sensors 208) on the structure 200. For example, a user can apply a force to a portion of the second surface 214 to provide an input measured by the sensors/components on the structure 200. In some examples, the user can touch, tap, squeeze, and/or apply pressure to the second surface 214 to provide an input (e.g., a touch input, a tap input, a squeeze/pressure input, etc.) that can be detected and measured by the touchpad 204, the display 206, and/or the sensors 208. In some examples, the user can provide a spinning or swiping force on the second surface 214 to generate an input (e.g., a spinning input, a swiping input, etc.) that can be detected and measured by the touchpad 204, the display 206, and/or the sensors 208. In some cases, the second surface 214 can include a touch or pressure sensitive surface and/or surface portion for measuring touch inputs.

In some cases, the receiving space 210 and/or the first surface 212 can be contoured and/or shaped to inhibit or prevent the structure 200 from rotating or spinning about a longitudinal axis of the user's finger and the receiving space 210 when the user applies a spinning or swiping force on the second surface 214. The touchpad 204, display 206, and/or sensors 208 can detect and measure the spinning or swiping force (e.g., a direction, magnitude, etc.) even if the structure 200 does not move or rotate (or movement or rotation of the structure 200 is substantially inhibited) in response to the spinning or swiping force. In other cases, the receiving space 210 and/or the first surface 212 can be contoured and/or shaped to allow the structure 200 to at least partly rotate/spin about a longitudinal axis of the user's finger and the receiving space 210 when the user applies a spinning or swiping force on the second surface 214. The touchpad 204, display 206, and/or sensors 208 can detect and measure the angular change, angular velocity, and/or angular acceleration of the structure 200 resulting from the spinning or swiping force.

In some examples, the ring device 150 can generate sensor measurements (e.g., via the touchpad 204 and/or sensors 208) and provide the sensor measurements to an electronic device (e.g., XR system 100, a mobile device, a television, a set-top box, any device with a user interface and/or any other electronic device) as inputs to an application on the electronic device. The sensor measurements can include measured interactions with the structure 200 and/or the second surface 214 (e.g., applied force/pressure, etc.), pose information about the structure 200, measured motion (e.g., rotation, velocity, acceleration, etc.), etc. The electronic device can interpret the sensor measurements into inputs to an application on the electronic device. In some examples, the ring device 150 can generate the sensor measurements and convert (e.g., process, interpret, map, etc.) the sensor measurements into inputs for an application running at the electronic device (e.g., XR system 100). The ring device 150 can use one or more processing devices of the ring device 150, such as an application-specific integrated circuit embedded in the structure 200, to convert the sensor measurements into inputs for a particular application. The ring device 150 can provide the inputs to the electronic device for processing by the particular application on the electronic device.

In some cases, the touchpad 204 and/or the sensors 208 can be used to generate a virtual spinning and/or rotating input by using one or more fingers to provide a force such as a spinning or swiping force. In some examples, the touchpad 204 and/or the sensors 208 can be used to generate a virtual spinning and/or rotating input by using one or more fingers to move the ring device 150 about a longitudinal axis of the receiving space 210. In some cases, the ring device 150 and/or a portion of the ring device 150 can rotate relative to the finger wearing the ring device 150, in response to a rotating force or gesture. In some examples, the sensors 208 can be used to provide a spinning and/or rotating input based on measurement movement of the ring device 150 about a longitudinal axis of the receiving space 210 and relative to the finger wearing the ring device 150.

In some examples, the ring device 150 can emit light using the display 206 and/or any light-emitting device (not shown) for detection by an electronic device with a camera, such as XR system 100. For example, the ring device 150 can emit light for detection by the electronic device. The electronic device can detect the light using one or more cameras and can use the light to determine motion of the ring device 150, such as rotation. In some examples, the ring device 150 can emit the light in response to a movement (e.g., rotation, etc.) above a threshold and/or a preconfigured interaction with the ring device 150 (e.g., with the second surface 214).

FIG. 2B illustrates another example of the ring device 150. In this example, the ring device 150 includes a structure 220 (or body) that has the receiving space 210 that provides a longitudinal access opening disposed on the underside of the structure 220 to allow at least ingress of a finger of a user, an engagement surface 222 that can engage a finger inserted through the receiving space 210 to wear the ring device 150, an upper surface 224, and a contact surface 226. The structure 220 can also include one or more sensors and/or electronic components as described herein. In some examples, the sensors 208 can include and/or can be the same as the IMU 152, the position sensor 154, the pressure sensor 156, and/or the touch sensor 158 shown in FIG. 1 . In other examples, the sensors 208 can include one or more sensors and/or devices that are not shown in FIG. 1 , such as one or more cameras, light sensors, audio sensors, lights, etc.

The receiving space 210 can be configured to receive a finger of a user. For example, as previously explained, the receiving space 210 can include a longitudinal access opening disposed on the underside of the structure 220 to allow at least ingress of a finger of a user. The engagement surface 222 can provide a surface for engagement or retention of the finger of the user. The engagement surface 222 can be contoured and/or shaped so as to support/retain the finger of the user within the receiving space 210 and inhibit or prevent movement of the finger in the longitudinal, lateral, and/or transverse axes/directions relative to the receiving space 210.

The upper surface 224 can include a top or partially external surface portion of the structure 220. The contact surface 226 can include another top or external surface portion of the structure 220. In some examples, the contact surface 226 (and/or a portion thereof) can be at least partially on top of and/or adjacent to the upper surface 224. In some cases, the contact surface 226 can be rotatably coupled to a portion of the upper surface 224. In some examples, the contact surface 226 can rotate about a longitudinal axis of the receiving space 210 and the upper surface 224. For example, the contact surface 226 can rotate relative to the upper surface 224 in a lateral direction from a longitudinal axis of the receiving space 210. The sensors 208 can measure the rotation (e.g., angular change, angular velocity, angular acceleration, etc.) and provide the measured rotation as input to an electronic device or convert the measured rotation into an input to an electronic device. In some cases, the contact surface 226 can include a touch or pressure sensitive surface and/or surface portion for measuring touch inputs.

In some examples, a user wearing the ring device 150 on a finger can interact with the contact surface 226 (e.g., using a different finger than the finger wearing the ring device 150 and/or using any other object) to provide inputs measured by the sensors 208 on the structure 220. For example, a user can apply a force to a portion of the contact surface 226 to provide an input measured by the sensors 208 on the structure 220. In some examples, the user can touch, tap, squeeze, and/or apply pressure to the contact surface 226 to provide an input (e.g., a touch input, a tap input, a squeeze/pressure input, etc.) that can be detected and measured by the sensors 208. In some examples, the user can provide a spinning or swiping force on the contact surface 226 to generate an input (e.g., a spinning input, a swiping input, etc.) that can be detected and measured by the sensors 208. In some examples, the user can rotate the contact surface 226 relative to the upper surface 224 (and about a longitudinal axis of the receiving space 210) to generate an input based on the rotation. The sensors 208 on the structure 220 can measure one or more properties of the rotation (e.g., angular change, angular velocity, angular rotation, etc.), which can be used as inputs and/or to generate inputs.

In some cases, the receiving space 210 and/or the engagement surface 222 can be contoured and/or shaped to inhibit or prevent the structure 220 from rotating or spinning about a longitudinal axis of the user's finger and the receiving space 210 when the user applies a spinning or swiping force on the upper surface 224. The sensors 208 can detect and measure the spinning or swiping force (e.g., a direction, magnitude, etc.) even if the structure 220 does not move or rotate (or movement or rotation of the structure 220 is substantially inhibited) in response to the spinning or swiping force. In other cases, the receiving space 210 and/or the engagement surface 222 can be contoured and/or shaped to allow the structure 220 and/or the contact surface 226 to at least partly rotate/spin about a longitudinal axis of the user's finger and the receiving space 210 when the user applies a spinning or swiping force on the contact surface 226. The sensors 208 can detect and measure the angular change, angular velocity, and/or angular acceleration of the structure 220 and/or the contact surface 226 resulting from the spinning or swiping force.

In some examples, the ring device 150 can generate sensor measurements (e.g., via the sensors 208) and provide the sensor measurements to an electronic device (e.g., XR system 100, a mobile device, a television, a set-top box, any device with a user interface and/or any other electronic device) as inputs to an application on the electronic device. The sensor measurements can include measured interactions with the structure 220 and/or the contact surface 226 (e.g., applied force/pressure, etc.), pose information about the structure 220, measured motion (e.g., rotation, velocity, acceleration, etc.), etc. The electronic device can interpret the sensor measurements into inputs to an application on the electronic device. In some examples, the ring device 150 can generate the sensor measurements and convert (e.g., process, interpret, map, etc.) the sensor measurements into inputs for an application running at the electronic device (e.g., XR system 100). The ring device 150 can use one or more processing devices of the ring device 150, such as an application-specific integrated circuit embedded in the structure 220, to convert the sensor measurements into inputs for a particular application. The ring device 150 can provide the inputs to the electronic device for processing by the particular application on the electronic device.

In some cases, the sensors 208 can be used to generate a virtual spinning and/or rotating input by using one or more fingers to provide a force such as a spinning or swiping force. In some examples, the sensors 208 can be used to generate a virtual spinning and/or rotating input by using one or more fingers to move the ring device 150 or the contact surface 226 about a longitudinal axis of the receiving space 210. In some cases, the ring device 150 and/or the contact surface 226 can rotate relative to the finger wearing the ring device 150, in response to a rotating force or gesture. In some examples, the sensors 208 can be used to provide a spinning and/or rotating input based on measured movement of the ring device 150 or the contact surface 226 about a longitudinal axis of the receiving space 210 and relative to the finger wearing the ring device 150.

In some examples, the ring device 150 can emit light using a light-emitting device (not shown) for detection by an electronic device with a camera, such as XR system 100. For example, the ring device 150 can emit light for detection by the electronic device. The electronic device can detect the light using one or more cameras and can use the light to determine motion of the ring device 150, such as rotation. In some examples, the ring device 150 can emit the light in response to a movement (e.g., rotation, etc.) above a threshold and/or a preconfigured interaction with the ring device 150 (e.g., with the contact surface 226).

FIG. 2C illustrates an example of the ring device 150 worn on a finger 240 of a user interacting with the XR system 100. In this example, the ring device 150 is used to interact with (e.g., provide inputs, etc.) the XR system 100. However, the XR system 100 is shown as a non-limiting example for explanation purposes. In other examples, the ring device 150 can be used to interact with other electronic devices (e.g., mobile devices, televisions, smart wearable devices, any electronic device with a user interface, etc.).

The user can use the ring device 150 to interact with the XR system 100 and provide various types of XR inputs as further described herein. In some examples, the ring device 150 can collect sensor measurements to track a location and/or pose of the ring device 150 in 3D space. In some examples, the location and/or pose can be tracked relative to a location and/or pose of the XR system 100 in 3D space.

In the example shown in FIG. 2 , the ring device 150 includes a touchpad 204 for receiving touch inputs, a display 206 for displaying information from the ring device 150 and/or the XR system 100, and sensors 208. In some examples, the sensors 208 can include and/or can be the same as the IMU 152, the position sensor 154, the pressure sensor 156, and/or the touch sensor 158 shown in FIG. 1 . In other examples, the sensors 208 can include one or more sensors and/or devices that are not shown in FIG. 1 , such as one or more cameras, light sensors, gyroscopes that are separate from a gyroscope of the IMU, accelerometers that are separate from an accelerometer of the IMU, magnetometers that are separate from a magnetometer of the IMU, audio sensors, lights or light emitting devices, transmitters, ultrasonic transmitters/transducers, etc. In some cases, the ring device 150 can include a touch or pressure sensitive surface and/or surface portion for measuring touch inputs.

In some cases, the touchpad 204 and/or the sensors 208 can be used to generate one or more measurements based on detected motion of the ring device 150, interactions with the ring device 150 (e.g., force/pressure/touch/rotation/etc.), a detected pose of the ring device 150, etc. In some cases, the ring device 150 can send such measurements to the XR system 100 as inputs to the XR system 100 (e.g., input to an XR application on the XR system 100). In some cases, the ring device 150 can convert/interpret (e.g., via an ASIC or any other processing device) the one or more measurements to one or more inputs on a user interface and/or XR application at the XR system 100, and send the one or more inputs to the XR system 100. In some cases, the touchpad 204 and/or the sensors 208 can be used to generate a virtual spinning and/or rotating input by using one or more fingers to provide a force such as a spinning or swiping force. In some examples, the touchpad 204 and/or the sensors 208 can be used to generate a virtual spinning and/or rotating input by using one or more fingers to move the ring device 150 about a longitudinal axis of the ring lumen (e.g., receiving space 210) while the ring device 150 remains substantially stationary relative to the finger 240. In some cases, the ring device 150 and/or a portion of the ring device 150 can rotate relative to the finger 240 in response to a rotating force or gesture. In some examples, the sensors 208 can be used to provide a spinning and/or rotating input by moving the ring device 150 about a longitudinal axis of the ring lumen and relative to the finger 240.

The XR system 100 can render content, interfaces, and/or controls to a user wearing the XR system 100. The user can use the ring device 150 to wirelessly interact with the content, interfaces, and/or controls and provide various types of inputs such as selections, object/environment manipulations, navigation inputs (e.g., scrolling, moving, etc.), gestures, etc. Non-limiting examples of interactions with content, interfaces, and/or controls rendered by the XR system 100 using the ring device 150 can include item scrolling in any kind of list and/or inventory of options, text scrolling in an object and/or rendered content item (e.g., a browser, a document, an interface, etc.), navigating to a different location and/or page, a data entry (e.g., a text and/or numerical entry, etc.), object and/or environment manipulation (e.g., object and/or environment rotation, translation, placement, and/or scaling), selection events, virtual space creation and/or manipulation, content scrolling, multimedia controls (e.g., start, stop, pause, etc.), physical world measurements, tracking and/or localization inputs and/or calibrations, etc.

The ring device 150 can provide privacy with respect to inputs, interactions, and/or associated data. For example, inputs can be provided via the ring device 150 discreetly and/or hidden from a field-of-view of a nearby device and/or person to avoid detection and/or recognition. Moreover, inputs can be provided via the ring device 150 while in space-constrained environments (e.g., tight spaces), while lying down and/or while a user is otherwise unable to provide (and/or has difficulty providing) inputs requiring additional and/or larger ranges of body (e.g., hand, arm, etc.) motion. For example, a user can provide inputs via the ring device 150 without waving a hand(s) and/or finger(s) in the air and/or away from the user's body. Moreover, in many cases, inputs provided via the ring device 150 can be easier and/or more intuitive. For example, the input gesture can mimic the type of input provided to the XR system 100 (e.g., rotating the ring device 150 to scroll, tapping the ring device 150 to select, etc.). In some cases, the ring device 150 can conserve power on the XR system 100 by power down or off (or providing information used to power down or off) tracking sensors on the XR system 100, such as image sensors.

FIG. 3A illustrates an example configuration 300 of a ring device 150. In this example, the ring device 150 includes an inner ring portion 310 (e.g., upper surface 224 shown in FIG. 2B) and an outer ring portion 312 (e.g., contact surface 226 shown in FIG. 2B). The inner ring portion 310 can receive/engage a finger 302 of a user as shown in FIG. 3A. In some examples, the outer ring portion 312 (and/or a portion thereof) can be at least partially on top of and/or adjacent to the inner ring portion 310. In some cases, the outer ring portion 312 (and/or a portion thereof) can encompass (and/or rotate) a greater distance along a lateral axis from a longitudinal axis of the lumen of the ring device 150 and at least a portion of the finger 302. In some examples, the inner ring portion 310 and the outer ring portion 312 can be asymmetric. In some cases, the outer ring portion 312 can be rotatably coupled to a portion of the upper surface 224. The outer ring portion 312 can spin/rotate relative to the inner ring portion 310 and around a longitudinal axis of the lumen of the ring device 150. The outer ring portion 312 can spin/rotate relative to the inner ring portion 310 in response to a force applied to the outer ring portion 312, such as a swiping force.

In some examples, the outer ring portion 312 can do a full rotation (e.g., 360 degrees) relative to the inner ring portion 310 and around a longitudinal axis of the lumen of the ring device 150. In other examples, the outer ring portion 312 can do a partial rotation (e.g., less than 360 degrees) relative to the inner ring portion 310 and around a longitudinal axis of the lumen of the ring device 150. In some cases, the amount of rotation can depend on the amount of rotational force/pressure (e.g., the magnitude and/or continuity) applied to the outer ring portion 312. For example, a user can apply a higher magnitude of force/pressure to the outer ring portion 312 to increase the amount of rotation performed by the outer ring portion 312. As another example, a user can apply a lower magnitude but continuous force/pressure to the outer ring portion 312 to increase the amount of rotation. Similarly, the user can decrease the amount of rotation by decreasing the amount (e.g., magnitude and/or continuity) of force/pressure applied to the outer ring portion 312.

When the outer ring portion 312 is rotated, a position sensor (e.g., position sensor 154) on the ring device 150 can determine the relative motion between the inner ring portion 310 and the outer ring portion 312. The position sensor can determine the magnitude of the rotation, the direction of the rotation, and/or the velocity of the rotation. The ring device 150 can provide rotation information to the XR system 100, which the XR system 100 can convert (e.g., interpret) into a particular XR input. In some cases, the XR input can correspond to the detection of relative motion. In some cases, the XR input can depend on more granular motion information such as the magnitude of rotation, the direction of rotation, and/or the velocity of rotation, as previously explained. For example, different directions of rotation can be converted (e.g., interpreted) into different XR inputs or types of XR input. To illustrate, a rotation in one direction can convert (can be interpreted as) to scrolling in a particular direction and a rotation in a different direction can convert to scrolling in a different direction. In some cases, rotation in one direction can be converted (e.g., interpreted as) to a type of XR input such as scrolling, while rotation in another direction can be converted to a different type of XR input such as a selection event, a different navigation event, etc.

As another example, different magnitudes of rotation (e.g., degrees) and/or velocities can convert into different XR inputs and/or different types of XR inputs. To illustrate, a rotation having a threshold magnitude and/or velocity can be converted into an autoscrolling or smooth scrolling event, and a rotation having a magnitude and/or velocity below a threshold can be converted into (e.g., interpreted as, mapped to, etc.) a certain magnitude of scrolling. In some cases, a rotation having a threshold magnitude and/or velocity can be converted into particular type of XR input, such as scrolling, while a rotation having a magnitude and/or velocity below a threshold can be converted into a different type of XR input, such as a selection event.

In some implementations, the XR system 100 can maintain definitions of rotation events and/or parameters, which the XR system 100 can use to convert a rotation event into an XR input. For example, the XR system 100 can map one or more magnitudes, velocities, and/or directions of rotation to one or more XR inputs and/or types of XR inputs. The XR system 100 can use such mapping to convert rotation information received from the ring device 150 into a particular XR input. In some cases, the XR system 100 can map specific magnitudes and/or velocities or specific ranges of magnitudes and/or velocities to specific XR inputs and/or types of XR inputs.

In some examples, the user can use a finger to rotate the outer ring portion 312 relative to the inner ring portion 310. For example, with reference to FIG. 3B, the user can use a different finger 304 to rotate the outer ring portion 312 while the ring device 150 is worn on the finger 302. In the example shown in FIG. 3B, the different finger 304 is a thumb on the same hand as the finger 302 on which the ring device 150 is worn. However, the user can rotate the outer ring portion 312 with any finger or combination of fingers on the same or different hand as the finger 302 wearing the ring device 150. In some cases, the user can rotate the outer ring portion 312 without use of another finger. For example, in some cases, the user can rotate the outer ring portion 312 by swiping the outer ring portion 312 with a surface (e.g., a leg, a couch, a seat/chair, a table, a floor, etc.) or pressing the ring device 150 onto a surface while moving the finger 302 along the surface. To illustrate, the user can press the ring device 150 against the user's leg and move the finger 302 a certain amount along the leg to cause the outer ring portion 312 to rotate a certain amount.

In some cases, the entire ring device 150 can be rotated relative to the finger wearing the ring device 150 and about a longitudinal axis of the ring device's lumen. For example, in some cases, the ring device 150 may rotate relative to the finger and a position sensor can detect the rotation (and/or the magnitude, velocity, and/or direction of the rotation) of the ring device 150. The ring device 150 can also be configured to detect inputs based on one or more other types of motion, force, and/or interactions. FIGS. 4A through 4D illustrate example use cases for providing inputs using the ring device 150.

FIG. 4A illustrates an example use case 400 for providing an input to the XR system 100 via the ring device 150. In this example, the user can tap a surface of the ring device 150 to provide an input to the XR system 100. For example, the user can wear the ring device 150 on finger 402 and use a different finger 404 to tap a surface of the ring device 150. The different finger 404 in this example is a thumb on the same hand as the finger 402 on which the ring device 150 is worn. However, the user can tap a surface of the ring device 150 with any finger or combination of fingers on the same or different hand as the finger 402 wearing the ring device 150. In some cases, the user can also tap a surface of the ring device 150 using a different object or surface, such as a leg (e.g., by tapping the ring device 150 against the leg), a couch, a seat/chair, a table, a floor, etc.).

A position sensor (e.g., position sensor 154) on the ring device 150 can detect the tapping and/or one or more characteristics of the tapping such as a magnitude or length of time of the tapping. The ring device 150 can provide information about the tapping to the XR system 100, which can convert the tapping information into an XR input.

In some cases, the tapping (and/or a characteristic of tapping such as a magnitude or length of time) can be mapped to one or more XR inputs. For example, the tapping, the magnitude of tapping, and/or a length of time of the tap can be mapped to an XR input event, an input function in a virtual user interface, etc. In some cases, different magnitudes of tapping and/or different lengths of time of tapping can be mapped to different XR inputs and/or XR input types. For example, a tap of a threshold magnitude can be mapped to an XR input, such as a double click, and a tap below the threshold magnitude can be mapped to a different XR input, such as a single click. As another example, a tap where the length of time of the force applied on a surface of the ring device 150 is below a threshold can be mapped to an XR input while a longer tap where the length of time of the force applied on the surface of the ring device 150 is above a threshold can be mapped to a different XR input. In some cases, one or more patterns of taps can be converted into one or more XR inputs. For example, a certain sequence of taps can be mapped to one or more XR inputs and a different sequence of taps can be mapped to one or more different XR inputs. FIG. 4B illustrates another example use case 420 for providing an input to the XR system 100 via the ring device 150. In this example, the user is wearing the ring device 150 on finger 402, providing an input by squeezing the ring device 150 with adjacent finger 406 and adjacent finger 408. A touch sensor (e.g., touch sensor 158) on the ring device 150 can detect the squeezing and/or determine the magnitude and/or the length of time of the squeezing. The ring device 150 can provide the squeezing information to the XR system 100, which can convert the squeezing information into an XR input.

In some examples, the squeezing, the magnitude of squeezing, and/or the length of time of the squeezing can be mapped to one or more XR inputs. In some cases, different magnitudes and/or lengths of time of squeezing can be mapped to different XR inputs and/or XR input types. For example, a prolonged squeeze (e.g., above a threshold amount of time) can be mapped to a particular XR input, such as a double click, and a shorter squeeze (e.g., below a threshold amount of time) can be mapped to a different XR input, such as a single click. As another example, a harder squeeze (e.g., above a threshold amount of force/pressure) can be mapped to a particular XR input, and a softer squeeze (e.g., below a threshold amount of force/pressure) can be mapped to a different XR input.

FIG. 4C illustrates an example use case 440 of a ring device 150 being rotated relative to a finger 402 wearing the ring device 150 and about a longitudinal axis of a lumen (e.g., receiving space 210) of the ring device 150. In this example, the ring device 150 does not include an outer ring portion and an inner ring portion as shown in FIGS. 3A and 3B. The user can use a different finger 410 to rotate the entire ring device 150 around at least part of the finger 402 wearing the ring device 150 and about a longitudinal axis of the lumen of the ring device 150. In some examples, the user can rotate the ring device 150 about the longitudinal axis of the lumen in a lateral direction from the longitudinal axis of the lumen. The different finger 410 in this example is a thumb on the same hand as the finger 402 on which the ring device 150 is worn. However, the user can rotate the ring device 150 with any finger or combination of fingers on the same or different hand as the finger 402 wearing the ring device 150.

When the different finger 410 rotates the ring device 150, a position sensor (e.g., position sensor 154) on the ring device 150 can determine the magnitude, velocity, and/or direction of rotation of the ring device 150 about the longitudinal axis of the lumen of the ring device 150. The ring device 150 can provide such rotation information to the XR system 100, and the XR system 100 can convert the rotation information into a particular XR input, as previously explained.

FIG. 4D illustrates an example use case 460 for rotating the ring device 150 using adjacent fingers. In this example, the user can use adjacent finger 406 and/or adjacent finger 408 to rotate the ring device 150 relative to the finger 402 wearing the ring device 150 and about a longitudinal axis of the lumen of the ring device 150. For example, the user can rotate the ring device 150 about a longitudinal axis of the lumen in a lateral direction from the longitudinal axis. The user can use the adjacent finger 406 and/or adjacent finger 408 to rotate or swipe the ring device 150 in a particular direction. A position sensor on the ring device 150 can detect the rotation and provide rotation information to the XR system 100. The XR system 100 can convert the rotation information into one or more XR inputs. The XR system 100 can use one or more definitions mapping XR inputs to rotation events, as previously explained.

In some examples, the ring device 150 can shown in FIGS. 4A-D can be used to provide other inputs and/or data in addition to and/or instead of the XR inputs corresponding to the use cases 400, 420, 440, and 460 described above. For example, the ring device 150 can emit a light or blink to provide certain information to the XR system 100. The XR system 100 can detect the light/blinking using one or more image sensors, and can use the light/blinking as an input and/or to supplement other inputs. In some examples, the XR system 100 can use the detected light/blinking to track/estimate a location and/or motion (e.g., rotation) of the ring device 150. In other examples, the XR system 100 can interpret and/or convert the detected light/blinking to an instruction to perform a certain action, such as adjust a state of one or more components of the XR system 100 (e.g., a power mode of one or more components (turn on, turn off, increase a power mode, decrease a power mode, etc.), a processing performed by the XR system 100, etc.), trigger an action by the XR system 100 (e.g., render an object and/or interface, start or stop an operation, press or activate a button on the XR system 100, etc.), process an input to a user interface at the XR system 100, supplement an input based on an interaction with the ring device 150 (e.g., force/pressure, etc.).

In other examples, the ring device 150 can detect audio (e.g., via one or more audio sensors), such as a speech or voice input, and provide the audio to the XR system 100 and/or an input instruction generated from the audio). The XR system 100 can use audio from the ring device 150 to perform a certain action at the XR system 100, as previously described. In some cases, the ring device 150 can be used to generate any other type of input to the XR system 100. For example, in some cases, the ring device 150 can be used to generate a hand gesture (e.g., a fist, a flat palm, pointing a finger/hand, a hand motion, a hand signal, etc.). The hand gesture can be determined by one or more sensors on the XR system 100 and used to perform a certain action at the XR system 100, as previously described. In some examples, the determination of the hand gesture can be aided by data from one or more sensors on the ring device 150, such as an IMU, a pressure sensor, etc.

FIG. 5 illustrates an example of a user 502 providing XR inputs by moving and/or positioning a hand 506 and/or finger 504 wearing the ring device 150. The user 502 can move the hand 506 and/or finger 504 in any direction in 3D space to generate one or more XR inputs via the ring device 150. The movement and/or position of the hand 506 and/or finger 504 can be converted into one or more XR inputs. In some cases, the movement of the hand 506 and/or finger 504 can be converted into one or more XR inputs based on a direction of movement, a magnitude of movement, a velocity of the movement, a pattern and/or sequence of the movement, a gesture associated with the movement, and/or any other characteristics of the movement.

As previously explained, the ring device 150 can implement sensors (e.g., IMU 152, position sensor 154, pressure sensor 156) that can measure characteristics of the movement. For example, the sensors on the ring device 150 can estimate the orientation of the finger 504 and/or hand 506 in 3D space, a movement of the ring device 150, a gesture associated with the finger 504 and/or hand 506, a position of the finger 504 and/or hand 506, etc. This information can be converted into one or more XR inputs. In some cases, this information can be converted into a manipulation of a virtual environment, interface, and/or object(s) presented by the XR system 100.

For example, in some cases, the sensor information from the ring device 150 can be used to track the hand 506 of the user 502. The hand tracking can be used to detect a hand gesture and trigger an object manipulation event. The ring device 150 can provide the sensor information to the XR system 100, which can convert the sensor information into an object manipulation, such as moving an object, rotating an object, resizing an object, setting a plane associated with an object and/or environment, etc.

As another example, the sensors in the ring device 150 can detect motion information (e.g., velocity, changes in acceleration, etc.) and provide the motion information to the XR system 100. The motion (e.g., velocity, changes in acceleration, etc.) reflected in the motion information can trigger certain events. The XR system 100 can convert the motion information and implement the triggered events. To illustrate, if the user 502 moves the hand 506 at a velocity and/or an acceleration above a threshold, the movement of the hand 506 can be converted into an event such as, for example, placing an object on a plane in 3D space and/or the virtual environment. In another example, the sensors in the ring device 150 can detect an orientation of the ring device 150 provide the orientation information to the XR system 100 with or without other information such as rotation information (e.g., rotational velocity, rotational acceleration, rotation angle, etc.). The orientation reflected in the orientation information can trigger certain events (e.g., with or without the other information such as the rotation information). The XR system 100 can convert the orientation information (with or without other information such as the rotation information) and implement the triggered events.

In some examples, the ring device 150 can use one or more sensors, such as ultrasonic transmitters/transducers and/or microphones, for ranging of the hand 506. The ranging of the hand 506 can be used to determine one or more XR inputs. For example, in some cases, ranging information can be used to resize objects with certain pinch gestures (e.g., one or more pinch gestures that gesture grabbing one or more edges of an object). In some cases, the ranging information (and/or other hand tracking information) associated with one or more ring devices can be used to implement resizing events based on certain gestures. For example, instead of finding and pinching the corners of an object, the user 502 can make a symbolic gesture with the user's hands for “resizing”. In some examples, the symbolic gesture can include a movement or gesture of one or more hands that mimics a motion used to resize an object, mimics a motion to define one or more boundaries/dimensions of an object, matches a preconfigured motion or gesture for resizing objects, etc. In some examples, a measurement of the distance between a ring device on each hand can then be used to affect the resizing of that object.

The ring device 150 can also be used to measure distances in the environment even when the ring device 150 is out of a field-of-view (FOV) of the XR system 100 or when the lighting levels in the environment are too low for the XR system 100 to sufficiently detect the ring device 150. For example, the user 502 can put down the hand 506 with the ring device 150 to trigger the ring device 150 to measure one or more distances in the physical world in an XR application, such as an XR measuring tape application for example. In some examples, the one or more distances to measure can be defined by a movement of the hand 506 with the ring device 150. For example, the user 502 can move the hand 506 with the ring device 150 from a first position to a second position to define a distance to be measured and/or initiate the start and end of the distance measurement. In some cases, the ring device 150 can use sensors, such as one or more ultrasonic transmitters/transducers and/or microphones, to determine if the user's hands are closer together or farther apart, if any of the user's hands are close to one or more objects, etc.

In some examples, the ring device can use a pressure sensor, such as a barometric air pressure sensor, to determine relative changes in the position of the hand 506. The XR system 100 can interpret such changes and/or position into XR inputs, such as selection events.

In some cases, the ring device 150 can use one or more sensors to obtain hand tracking information, which the XR system 100 can use to track the hands and/or estimate a location of the hands even if the hands are out of the FOV of the XR system 100 and/or the lighting is too low for the image sensor at the XR system 100 to detect the hands. For example, if the user's hands move from up to down while outside of the FOV of the XR system 100, the XR system 100 can still obtain an estimate of such motion. In some cases, the XR system 100 can implement a synthetic animation representing such motion even though such motion occurred outside of the FOV of the XR system 100.

In some examples, the XR system 100 can determine XR inputs based on a combination of motion/position information from the ring device 150 and interactions with the ring device 150. For example, the ring device 150 can send to the XR system 100 sensor measurements of a hand position and a rotation (e.g., angle, rotational velocity, and/or rotational acceleration) of the ring device 150. The XR system 100 can use the combination of the hand position and the rotation (e.g., the angle, rotational velocity, and/or rotational acceleration) of the ring device 150 to enable vertical and horizontal adjustments of virtual objects and/or environments. To illustrate, the user can create a plane in space using the hand with the ring device 150. The user can then adjust the height and depth of that plane by a spin or scroll action of the ring device 150. The hand orientation reported by the ring device 150 (e.g., vertical and/or horizontal) can determine which component (e.g., height or depth) the user is modifying.

As another example, the user can setup a virtual space, such as a virtual office, by “setting” anchor planes based on the hand position measured based on sensor data from the ring device 150. The user can scroll through different content elements to position one or more content elements (e.g., a TV screen, weather widget, TV monitor, game, etc.) on one or more anchor planes. The user can also use the ring device 150 to provide content scrolling and multimedia controls (e.g., start, stop, pause, etc.). For example, if the user has a media application, such as a music application or a video application, the user can start, stop, pause, rewind, forward, and/or otherwise control a content playback on the media application without moving the user's hands. The user can instead control the media application by interacting with the ring device 150, such as applying pressure to the ring device 150, rotating the ring device 150, etc.

FIG. 6 is a flowchart illustrating an example process 600 for using a ring device (e.g., ring device 150) to enhance user interface, input, and/or XR functionalities. At block 602, the process 600 can include detecting, by a wearable device (e.g., ring device 150), movement of the wearable device and/or a force applied to a surface(s) of the wearable device. In some examples, the wearable device can include a structure defining a receiving space or lumen (e.g., receiving space 210) configured to receive a finger associated with a user. In some examples, the structure can include a first surface configured to contact the finger received via the receiving space. In some examples, the receiving space can include a longitudinal access opening for receiving the finger, and the first surface can be countered or shaped to inhibit or prevent a movement of the finger along a longitudinal, lateral, and/or transverse direction.

At block 604, the process 600 can include determining, by the wearable device from one or more sensors on the wearable device, one or more measurements of the movement of the wearable device and/or the force applied to the surface(s) of the wearable device. In some examples, the one or more sensors are integrated into the structure associated with the wearable device. In some examples, the one or more measurements can include a rotation of at least a portion of the wearable device about a longitudinal axis of the receiving space associated with the wearable device. In some cases, the one or more sensors can be configured to detect the rotation of at least a portion of the wearable device about the longitudinal axis of the receiving space. In some cases, the one or more measurements can include a first rotational measurement (e.g., angular change, angular/rotational velocity, angular/rotational acceleration, etc.) associated with a first rotation of the structure about the longitudinal axis of the receiving space of the wearable device and/or a second rotational measurement (e.g., angular change, angular/rotational velocity, angular/rotational acceleration, etc.) associated with a second rotation of a portion of the structure about the longitudinal axis of the receiving space. The first rotation and the second rotation can be relative to the finger contacting the first surface of the wearable device.

At block 606, the process 600 can include sending, by the wearable device via a wireless transmitter, to an electronic device (e.g., XR system 100), data associated with the one or more measurements. In some examples, the wearable device can send the one or more measurements of the movement to the electronic device. The one or more measurements can represent and/or correspond to an XR input at the electronic device.

In some aspects, the process 600 can include sending, by the wearable device to the electronic device, an XR input associated with an XR application at the electronic device. In some examples, the XR input can be based on one or more measurements from the one or more sensors. For example, the XR input can include the first rotational acceleration and/or the second rotational acceleration.

In some examples, the one or more measurements of the movement include one or more rotational measurements, and the one or more rotational measurements include at least one of a rotational angle, a rotational velocity, and/or a rotational acceleration.

In some examples, the one or more sensors are configured to detect at least one of a touch signal corresponding to one or more fingers contacting a second surface of the structure, an orientation of the structure, and/or a position of the structure relative to one or more objects. In some cases, the data can include at least one of a magnitude of the touch signal, the orientation of the structure, the position of the structure relative to the one or more objects, and/or a distance between the structure and at least one of the electronic device directly or indirectly coupled to the wearable device and/or a different hand than a respective hand of the finger.

In some aspects, the one or more sensors can be configured to detect a touch signal corresponding to one or more fingers contacting a different surface of the structure, an orientation of the structure, and/or a position of the structure relative to one or more objects. In some cases, the one or more measurements can include a magnitude of the touch signal, the orientation of the structure, the position of the structure relative to the one or more objects, and/or a distance between the structure and the electronic device and/or a different hand than a respective hand of the finger. In some examples, the one or more measurements correspond to an additional orientation of the respective hand of the finger, and the XR input is based on the additional orientation of the respective hand and at least one of the rotation and/or the orientation of the structure.

In some examples, detecting the movement can include detecting a rotation of at least a portion of the structure about a longitudinal axis of the receiving space and measuring at least one of a first rotation of a first portion of the structure (e.g., upper surface 224) about the longitudinal axis of the receiving space and a second rotation of a second portion of the structure (e.g., contact surface 226) about the longitudinal axis of the receiving space. In some examples, the second rotation is in a direction opposite to the first rotation.

In some aspects, the process 600 can include sending, by the wearable device to the electronic device, one or more additional measurements from the one or more sensors. In some cases, the one or more additional measurements correspond to an additional orientation of the respective hand of the finger. In some examples, the XR input is based on the additional orientation of the respective hand and at least one of the first rotation, the second rotation, and/or the orientation of the structure.

In some cases, an XR input can include scrolling virtual content rendered by the electronic device, scaling an object rendered by the electronic device, rotating the object rendered by the electronic device, moving the object rendered by the electronic device, defining a virtual plane in an environment rendered by the electronic device, and/or placing a virtual object rendered by the electronic device in one or more virtual planes in the environment rendered by the electronic device. In some cases, the XR input can be based on a touch signal corresponding to one or more fingers contacting a second surface of the structure (e.g., second surface 214, contact surface 226), an orientation of the structure, rotation of the wearable device, a movement of a hand associated with the finger, and/or a position of the structure relative to one or more objects.

In some examples, the XR input can be based on one or more properties associated with the one or more measurements. In some cases, the one or more properties can include a magnitude of rotation of the wearable device, a direction of the rotation, a velocity of the rotation, and/or a length of time of a pressure applied to one or more portions of the structure. The one or more properties can be identified by the one or more measurements.

In some cases, the XR input can be based on one or more properties associated with the touch signal. The one or more properties can include a magnitude of pressure from the one or more fingers contacting the second surface of the structure, a motion associated with the one or more fingers when contacting the second surface of the structure, a direction of the motion, a length of time of contact between the one or more fingers and the second surface, and/or a pattern of contact of the second surface of the structure by the one or more fingers. The one or more properties can be identified by the one or more measurements. In some examples, the pattern of contact can include a sequence of contacts by the one or more fingers on the second surface.

In some cases, the XR input can include modifying a virtual element along multiple dimensions in space. In some examples, the virtual element can include a virtual object rendered by the electronic device, a virtual plane in the environment rendered by the electronic device, and/or the environment rendered by the electronic device. In some examples, an adjustment of a first dimension of the multiple dimensions is defined by at least one of an angular change, a rotational velocity, and/or a rotational acceleration associated with a rotation of the wearable device. In some examples, an adjustment of a second dimension of the multiple dimensions is defined by one or more different measurements in the one or more measurements. In some cases, the one or more different measurements in the one or more measurements can include a touch signal corresponding to one or more fingers contacting a second surface of the structure, an orientation of the structure, and/or a position of the structure relative to one or more objects.

In some cases, the one or more measurements can include motion measurements corresponding to a movement of a hand associated with the finger. In some examples, the XR input can correspond to a request to measure a distance in physical space. The distance can be defined by the movement of the hand. For example, the distance can be defined by a first position of the hand prior to or during the movement of the hand, and a second position of the hand after or during the movement of the hand.

In some cases, the wearable device can reduce power consumption and resource usage at the electronic device. For example, the wearable device can offload certain operations such as hand tracking and/or other tracking operations from the electronic device, allowing the electronic device to reduce power consumption and resource usage such as sensor, camera, and/or compute resource usage. In some examples, when tracking operations are offloaded from the electronic device to the wearable device, the electronic device can turn off, or reduce a power mode of, one or more tracking resources such as cameras and/or other sensors that the electronic device would otherwise use to track the user's hands and/or other objects.

In some examples, the wearable device can be equipped with various power saving features. For example, in some cases, the wearable device can save power by shutting down after an XR application on the electronic device has stopped and/or been terminated. As another example, the wearable device can remain off or in a lower power mode, and turn on or switch to higher power mode based on one or more user interactions/inputs. For example, the wearable device can remain off or in a lower power mode, and turn on or switch to higher power mode when the wearable device is rotated by a certain amount.

In some cases, the wearable device can include a wearable ring. In some cases, the one or more sensors can include a position sensor, an accelerometer, a gyroscope, a magnetometer, a pressure sensor, an audio sensor, a touch sensor, and/or an inertial measurement unit.

In some examples, the process 600 may be performed by one or more computing devices or apparatuses. In one illustrative example, the process 600 can be performed by the XR system 100 and/or the ring device 150 shown in FIG. 1 and/or one or more computing devices with the computing device architecture 700 shown in FIG. 7 . In some cases, such a computing device or apparatus may include a processor, microprocessor, microcomputer, or other component of a device that is configured to carry out the steps of the process 600. In some examples, such computing device or apparatus may include one or more sensors configured to capture image data and/or other sensor measurements. For example, the computing device can include a smartphone, a head-mounted display, a mobile device, or other suitable device. In some examples, such computing device or apparatus may include a camera configured to capture one or more images or videos. In some cases, such computing device may include a display for displaying images. In some examples, the one or more sensors and/or camera are separate from the computing device, in which case the computing device receives the sensed data. Such computing device may further include a network interface configured to communicate data.

The components of the computing device can be implemented in circuitry. For example, the components can include and/or can be implemented using electronic circuits or other electronic hardware, which can include one or more programmable electronic circuits (e.g., microprocessors, graphics processing units (GPUs), digital signal processors (DSPs), central processing units (CPUs), and/or other suitable electronic circuits), and/or can include and/or be implemented using computer software, firmware, or any combination thereof, to perform the various operations described herein. The computing device may further include a display (as an example of the output device or in addition to the output device), a network interface configured to communicate and/or receive the data, any combination thereof, and/or other component(s). The network interface may be configured to communicate and/or receive Internet Protocol (IP) based data or other type of data.
